That is, the retaining rod 46 is pivotally mounted at its front end portion to the bracket 34 of the receiver body 31 by the front mounting hole 87a, and the shutter member 37 is at its front end portion by the rear mounting hole 87b Mounted on the bracket 34 in a pivotable manner.

The left rear mounting hole and the right rear mounting hole 87b are located above the socket support section 42 (see also Fig. 12A). Thus, the shutter member 37 has a pivot axis located above the socket support section 42.

The box holding section 34 includes a holding lever 46 pivotally supported at the front end portion thereof in the left front mounting hole and the right front mounting hole 87a, and a locking fastener 47 pivotally mounted to the retaining rod 46 And a spring member 49 for normally pushing the retaining rod 46 toward the receiver body 31 such that the gas cylinder 26 can be elastically pressed against the receiver body 31 and can be securely mounted to the receiver body 31.

The box holding section 34 can be used to cause the jaw gas cylinder 21 (gas cylinder 26) to be used by the socket by means of the socket support section/displacement valve unit 32 of the gas cylinder 21 (gas cylinder 26). The position at which the support section/displacement valve unit 32 is held is shifted from a position for canceling the hold.

The retaining rod 46 includes a left leg portion and a right leg portion 91, and the left leg portion and the right leg portion 91 have respective proximal end portions 91a pivotally supported in the left front mounting hole and the right front mounting hole 87a. And the left inclined portion and the right inclined portion 92 extend from respective distal ends of the left leg portion and the right leg portion 91. The respective distal ends (or upper ends) of the left inclined portion and the right inclined portion 92 are interconnected via a connecting portion 93.

The left leg portion and the right leg portion 91 of the retaining rod 46 are located outside of the gas cylinder box 26. The left inclined portion and the right inclined portion 92 extend upward from the outside of the gas cylinder 26 toward the longitudinal centerline of the gas cylinder 26, in such a manner that the connecting portion 93 can be positioned to engage the engaging portion 48 of the gas cylinder 26.

A spring member 49 for normally pushing the retaining rod 46 toward the cylinder case 26 is wound around a portion between the right extension portion 87 of the right leg portion 91 and the proximal end portion 91a of the right leg portion 91, and the spring member 49 has one end portion 49a engaged by the right extension portion 87 and the other end portion (not shown) engaged by the right leg portion 91.

The present embodiment, in which the left holding force generating portion and the right holding force generating portion 86 are provided on the support bracket 33 of the support box holding portion 34, holds the gas cylinder 21 by elastically deforming the holding force generating portion 86. (Gas cylinder box 26). By this elastic deformation, a restoring force for returning the left holding force generating portion and the right holding force generating portion 86 to their original positions is generated. The restoring force of the left holding force generating portion and the right holding force generating portion 86 acts on the gas cylinder 21 via the gas cylinder 26 so that the gas cylinder 21 can be reliably held.

Since the portion of the support bracket 33 (i.e., the left holding force generating portion and the right holding force generating portion 86) is designed to function as an elastically deformable portion, the original gas cylinder 21 (gas cylinder) can be omitted. Box 26) requires a spring component. Therefore, the number of necessary component parts can be reduced, and thereby the configuration is simplified and the manufacturing cost of the 气体 gas cylinder mounting structure is reduced.

The valve interlocking section 35 includes a driven section 98 that extends from the operating lever 82. The driven section 98 includes a driven base portion 101 extending from the operating lever 82 toward the left leg portion 91 and a driven locking portion 102 disposed on the driven base portion 101. The driven locking portion 102 having a generally inverted L shape has a curved portion 102a engageable with the left leg portion 91 from the front of the machine.

In the valve interlocking section 35, when the operating lever 82 is displaced to the fuel supply position P1 (see FIG. 6) with the helium gas cylinder 21 held by the tank holding section 34, the curved portion 102a abuts against On the left leg portion 91.

When the tank holding section 34 (more specifically, the retaining rod 46) is moved to the one cancel position P4 (see FIG. 7) for canceling the holding of the helium gas cylinder 21, the bending can be performed by the left leg portion 91. The movement of the portion 102a shifts the operating lever 82 from the fuel supply position P1 to the fuel blocking position P2 (see Fig. 7).

That is, by providing the valve interlocking section 35, when the holding of the cartridge holding section 34 for the holding of the helium gas cylinder 21, the shift valve 43 can be interlocked with the movement of the retaining rod 46 from the fuel supply position. Shift to the fuel blocking position.

The shutter member 37 includes: a shutter body 105 for closing the socket support section 42; a support pin (support shaft) 106 that mounts the shutter body 105 to the left extension portion and the right extension portion 87 (more Specifically, the left rear mounting hole and the right rear mounting hole 87b); a shutter spring member 107 that normally pushes the shutter body 105 toward the socket supporting section 42 to thereby normally The shutter member 37 is pushed to a closed position P5 (see Fig. 6).

The shutter spring member 107 is wound around a portion between the left extension portion 87 of the support pin 106 and the shutter member 37, and the shutter spring member 107 has one end portion 107a engaged by the left extension portion 87 and by the shutter member 37. The other end portion of the meshing (not shown).

The shutter body 105 is pivotally supported at its front end portion by a left rear mounting hole and a right rear mounting hole 87b via a support pin 106 when the 匣 gas cylinder 21 (gas cylinder 26) is detached from the receiver mechanism 25. The baffle body 105 closes the socket support section 42 by the biasing force of the baffle spring member 107.

The baffle body 105 includes a plate portion 111 for closing one of the generally rectangular shapes of the socket support section 42 and a peripheral side wall 112 bent from the outer periphery of the plate portion 111. More specifically, the peripheral side wall 112 extends away from the rear surface 111a of the plate portion 111, and has a concave portion 112b formed in the rear wall portion 112a thereof to extend along one of the upper walls 26a of the gas cylinder case 26. Therefore, the concave portion 112b of the peripheral side wall 112 of the baffle body 105 can be fitted over the upper wall 26a of the gas cylinder case 26.

In the foregoing state, the peripheral side wall 112 abuts against the upper wall 26a of the gas cylinder case 26. Therefore, the rear surface 111a of the plate portion 111 can be held in a substantially sealed closed state by the peripheral side wall 112 and the upper wall 26a of the gas cylinder case 26, so that foreign matter such as sand and dust can be prevented from adhering to the rear surface 111a of the plate portion 111. .

As mentioned above, the left rear mounting hole and the right rear mounting hole 87b are located above the socket support section 42, and thus the support pin 106 is located above the socket support section 42. Thus, the baffle body 105 can close and open the socket support section 42 from above the socket support section 42. In this way, foreign matter such as dust can be prevented from entering and adhering to the nozzle receiving portion 65 of the socket support section 42.

Since the support pin 106 of the shutter member 37 is located above the socket support section 42, when the shutter member 37 is in its open position, the front surface 111b of the plate portion 111 faces upward while the rear surface 111a of the plate portion 111 faces downward. Since the rear surface 111a of the plate portion 111 faces downward, foreign matter such as sand and dust can be prevented from falling on the rear surface 111a.

In addition, since the peripheral side wall 112 abuts against the upper wall 26a of the gas cylinder 26 in the case where the concave portion 112b of the peripheral side wall 112 is fitted over the upper wall 26a, the peripheral side wall 112 and the gas can be used. The upper wall portion 26a of the crockette 26 holds the rear surface 111a in a substantially sealed closed state so that foreign matter such as sand and dust can be prevented from adhering to the rear surface 111a of the plate portion 111.

Since the current example can prevent foreign matter such as sand and dust from falling on the rear surface 111a of the plate portion 111 in the foregoing manner, it can reliably prevent such as sand and dust when the surface 111a closes the socket support portion 42 by the plate portion 111. The foreign matter enters the socket support section 42 (specifically, the nozzle receiving portion 65).

When the human operator cancels the holding of the helium gas cylinder 21 (gas cylinder 26) by the tank holding section 34, the flap interlocking section 38 displaces the shutter member 37 in an interlocking relationship with the holding canceling operation. To the open position. The flap interlocking section 38 includes an engagement member 115 that is engageable with the right leg portion 91 of the box holding section 34.

The engaging member 115 includes a projecting portion 116 projecting upward from the peripheral side wall 112 (more specifically, a front end portion of the right side wall portion 112c) and a top portion 116a of the self-extending portion 116 extending substantially horizontally toward the right leg portion 91. One of the protrusions 117.

In the case where the engaging member 115 is integrally formed with the shutter member 37, the biasing force of the shutter spring member 107 can be used to cause the projection 117 to engage the right leg portion 91 from the front of the machine.

Therefore, when the human operator operates the box holding section 34 to cancel the holding of the cartridge gas cylinder 21 by the tank holding section 34, it can be mutually reciprocated by the simple configuration of only one of the engaging members 115 and the human operator. The shutter member 37 is displaced in a lock relationship to the open position P6 (Fig. 7).

The upper front wall portion 156 has an upper opening recess 145, and the upper convex portion 148 is formed along the periphery of the upper opening recess 145. Further, the upper rear wall portion 157 has an upper hinge portion 161 of one of the hinge sections 124 formed thereon, and the upper hinge portion 161 includes a left end region and a right end region formed on the lower edge 157a of one of the rear wall portions 157. The hinge portion and the upper right hinge portion 162 (see also Figure 10).

The upper left hinge portion and the upper right hinge portion 162 have a left upper through hole and a right upper through hole 163 concentric with the lower through hole 152, and the left upper through hole and the right upper through hole 163 are extended through the hinge pin 153 Hole.

The locking section 125 includes a left locking hole and a right locking hole 136 formed in the lower case half 123 and a left locking claw and a right locking claw 137 provided on the upper case half 122. The upper box half 122 and the lower box half 123 can be held in a closed position by engaging the left locking pawl 137 in the left locking hole 136 and locking the right locking pawl 137 in the right locking hole 136.

The opening portion 27 is formed in the front wall portion (i.e., the upper front wall portion and the lower front wall portions 156 and 132) and is coaxial with the helium gas cylinder 21 accommodated therein. The opening portion 27 has a diameter smaller than the socket portion 61 (more specifically, the flange 72) of the 匣 gas cylinder 21. Therefore, one of the annular abutment portions 168 abutting against the flange 72 of the helium gas cylinder 21 is formed on one of the front wall portions 26c of the gas cylinder case 26.

An annular groove 126 including a lower annular groove portion 141 and an upper annular groove portion 142 is formed in a rear end portion of one of the inner peripheral wall surfaces of the gas cylinder case 26. More specifically, the annular groove 126 is formed adjacent to one of the annular inclined wall portions 167 having an inner surface that is gradually outwardly and forwardly inclined (i.e., has an inner diameter that gradually increases toward the front). The bottom portion 21c of the 气体 gas cylinder 21 remains abutted against the inner surface of the inclined wall portion 167.

The annular sloping wall portion 167 is provided for pushing the bottom portion 21c of the gas cylinder 21 forward when the upper and lower tank halves 122 and 123 are closed. The gas cylinder 21 of the gas cylinder 21 is appropriately held in the gas cylinder 26 by the inclined wall portion 167 pushing the bottom portion 21c of the gas cylinder 21, wherein the socket portion 61 (more specifically, the flange 72) The abutment abuts against the abutment portion 168 of the gas cylinder bin 26.

Referring again to Fig. 5, the annular projection portion 128 is formed concentrically with the opening portion 27 and annularly along the peripheral edge of the opening portion 27 in the front wall portion 26c of the gas cylinder case 26 (see also Figs. 8 and 9).

The fitting recessed portion 170 is formed in one end portion of the gas cylinder case 26 to extend along the annular projecting portion 128 and coaxial with the axis of the gas cylinder case 26. The inner peripheral wall portion 171 defining the fitting recessed portion 170 has a circular cross-sectional shape. When viewed in a longitudinal or axial cross-sectional view, the inner peripheral wall portion 171 has a wall thickness which is gradually reduced in such a manner that its surface faces one end portion or one of the front end or the distal end 171a of the fitting concave portion 170. The outer peripheral wall portion 171 is gradually inclined outward, that is, the inner diameter of the inner peripheral wall portion 171 gradually increases toward the front end or the distal end 171a. As will be explained later, when the cylinder case 26 with the helium gas cylinder 21 is attached to the socket support section 42 of the receiver mechanism 25, the surface of the inner peripheral wall portion 171 can serve as a mounting guide surface.

In the case where the inner peripheral wall portion 171 has such a gradually decreasing wall thickness (i.e., the inner diameter gradually increases toward the front end or the distal end 171a, when viewed in an axial sectional view), it can be used as an installation. The surface of the inner peripheral wall portion 171 of the guide surface easily guides the socket portion 61 of the gas cylinder 21 to be coaxially aligned with the socket support portion 42 (see Fig. 4). That is, in the case where the inner diameter of the inner peripheral wall portion 171 is gradually increased toward the distal end 171a in the aforementioned manner, the distal end 171a of the fitting concave portion 170 may have an increased inner diameter D. In this manner, when the gas cylinder case 26 is to be mounted to the receiver mechanism (cylinder mounting mechanism) 25, the human peripheral operator only appropriately positions the inner peripheral wall portion 171 with respect to the socket support portion 42, without a large amount of time The socket portion 61 of the helium gas cylinder 21 housed in the gas cylinder box 26 can be easily attached to the socket support section 42 with an effort.

Figure 10 is a cross-sectional view showing one of the hinge sections 124 of the gas cylinder case 26 used in the present embodiment, and Figure 11 is an enlarged view of one of the sections surrounded by 11 of Figure 10.

The hinge section 124 includes a lower hinge portion 151 formed on the lower rear wall portion 133 of the lower box half 123; an upper hinge portion 161 (left upper hinge portion and right upper hinge portion 162) formed in the upper box half a portion 122 on the upper rear wall portion 157; a hinge pin 153 pivotally interconnecting the upper hinge portion and the lower hinge portions 161 and 151; and a left anti-drop projection and a right anti-drop projection 165 It is used to prevent the hinge pin 153 from accidentally coming off from the hinge portions 161 and 151.

The left upper hinge portion 162 in which the upper through hole 163 is formed further has: an outer concave portion 162b formed in a lower outer end region thereof; and is formed in an upper portion thereof located in the middle of the upper left hinge portion 162 One of the concave portions 162a (see also FIG. 2); and an anti-drop protrusion 165 formed on the outer end surface 163a of one of the outer end portions defining the upper through hole 163.

The left fall prevention protrusion 165 is disposed on a region of the outer end surface 163a opposite to the outer concave portion 162b.

Since the upper left hinge portion 162 is constructed in such a manner that the inner concave portion 162a and the outer concave portion 162b are formed in the upper left hinge portion 162 and the left fall prevention projection 165 is disposed in the region opposite to the outer concave portion 162b Upper, and thus when the upper left hinge portion 162 is molded by resin injection, not only the upper through hole 163 but also the left fall prevention protrusion 165 can be easily formed.

In the foregoing manner, the left upper hinge portion 162 having the left fall prevention protrusion 165 can be easily formed. Note that the upper right hinge portion 162 is constructed and shaped to be bilaterally symmetric with the upper left hinge portion 162, and thus the right upper hinge portion 162 is explained hereinafter with the same reference numerals as used for the upper left hinge portion 162.

In the hinge section 124, the lower hinge portion 151 is disposed between and coaxial with the upper left hinge portion and the right upper hinge portion 162, and the hinge pin 153 extends through the left upper through hole and the right upper through hole 163 and the lower hinge portion 151 lower through hole 152. That is, the upper left hinge portion and the upper right hinge portion 162 and the lower hinge portion 151 are pivotally mounted to the hinge pin 153.

The left anti-drop protrusion and the right anti-drop protrusion 165 are formed on the surfaces of the left upper hinge portion and the upper right hinge portion 162 defining the left upper through hole and the right upper through hole 163. The left fall prevention protrusion 165 is disposed close to one of the left end portions 153a of the hinge pin 153, and the right fall prevention protrusion 165 is disposed close to one right end portion 153b of the hinge pin 153.

Therefore, the left fall prevention protrusion and the right fall prevention protrusion 165 can abut against the left end portion and the right end portions 153a and 153b of the hinge pin 153, respectively. In the foregoing manner, the left anti-drop projection and the right anti-drop projection 165 prevent the hinge pin 153 from accidentally falling out of the hinge section 124, which enhances the squat gas cylinder mounting structure and thus the usability of the machine.

Referring now to Figures 12 through 15, an illustration will be given of an exemplary manner of mounting a gas cylinder 21 to a receiver mechanism (i.e., a cylinder mounting mechanism) 25.

12A and 12B are illustrations of an exemplary manner of lifting the box holding section 34 to an evacuated position. As shown in FIG. 12A, the biasing force F1 of the spring member 49 (see FIG. 6) normally pushes the retaining rod 46 of the tank holding section 34 toward the bottom section 51 of the receiver body 31, so that The locking fastener 47 of the retaining rod 46 is held pressed against the bottom section 51 of the receiver body 31 by a spring member 49.

Further, the shutter member 37 abuts against the socket support section 42 by the spring force F2 of the shutter spring member 107 (see FIG. 6). In the foregoing manner, the socket support section 42 is closed by the shutter member 37 so that foreign matter such as sand and dust can be prevented from entering the socket support section 42 (specifically, the nozzle receiving portion 65).

In the foregoing state, the human operator pivots the holding lever 46 upward about the left leg portion and the proximal portion 91a of the right leg portion 91 as indicated by the arrow A so that the right leg portion 91 of the retaining lever 46 abuts It rests on the protrusion 117 of the baffle interlocking section 38. As the retention lever 46 continues to pivot further upward as indicated by arrow A, the projection 117 moves upwardly in interlocking relationship with the pivotal movement of the retention lever 46. Therefore, the shutter member 37 pivots upward about the support pin 106 as indicated by an arrow B.

Then, as shown in FIG. 12B, the retaining rod 46 is withdrawn to the cancel position P4 above the receiver body 31, and the shutter member 37 is moved upwardly in an interlocking relationship with the withdrawal movement of the retaining lever 46 to the open position P6. In order to open the socket support section 42.

Further, the cylinder case 26 in which the helium gas cylinder 21 is accommodated is brought close to the receiver mechanism 25, and the downwardly projecting portion 56 of the gas cylinder case 26 is placed on the bottom section 51 of the receiver body 31 as indicated by the arrow C. . Meanwhile, as indicated by an arrow D, the left slider and the right slider 59 (only the left slider 59 are displayed) are inserted into the left slider guide portion and the right slider guide portion 58 (only the right slider guide portion is displayed) 58) Medium.

In the foregoing manner, the gas cylinder 26 is mounted to the receiver body 31 such that the gas cylinder 21 (see FIG. 9) in the gas cylinder 26 is supported by the socket support section 42 as indicated by an arrow E.

13A and 13B are explanatory views of an exemplary manner in which the gas cylinder 21 is held by the receiver mechanism 25. As shown in Fig. 13A, as indicated by an arrow F, the biasing force F1 of the spring member 49 (see Fig. 6) causes the retaining lever 46 to pivot downwardly so that the locking end 47b of the locking fastener 47 abuts It abuts against the rear end portion 48a of the engaging portion 48.

That is, when the locking fastener 47 is moved as indicated by an arrow G, the locking end 47b is engaged in the engaging groove 48b of the engaging portion 48, during which the left holding force generating portion and the right holding force of the support bracket 33 are generated. Portion 86 is elastically deformed as indicated by an arrow H.

When the retaining rod 46 is pivoted downward by the biasing force F1 of the spring member 49 as mentioned above, the biasing force F2 of the shutter member 37 by the shutter spring member 107 (see Fig. 6) is as indicated by an arrow I. The indication is lowered. Therefore, the shutter member 37 abuts against the upper wall 26a of the gas cylinder 26 so that the shutter member 37 is held in a position in which it has abutted against the shutter spring member 107.

Then, as shown in FIG. 13B, the retaining rod 47 is positioned in the retaining position P3, and the gas cylinder 26 is held by the tank holding section 34. Therefore, in the case where the locking end 47b is engaged in the engaging recess 48b (see also FIG. 9), the connecting portion 93 is located below an imaginary line 95 connected between the left proximal end and the right proximal end 91a and the locking end 47b. That is, it is closer to the gas cylinder case 26 than the imaginary line 95.

Further, in the case where the locking end 47b is engaged in the engaging groove 48, a restoring force is generated in the left holding force generating portion and the right holding force generating portion 86 which are elastically deformed as indicated by an arrow H, and the restoring force thus generated Actuating on the locking fastener 47 via the retaining rod 46 is such that the locking fastener 47 is pressed against the gas cylinder 26 by the restoring force. In this manner, the locking end 47b is kept engaged in the engaging recess 48b of the engaging portion 48, and thus, the locking fastener 47 is held in the engaged state.

By the restoring force acting on the gas cylinder 21 (see Fig. 9) via the gas cylinder 26, manufacturing and assembly errors and the like can be absorbed. In this way, the xenon gas cylinder 21 is reliably held by reliably abutting against the socket support section 42 (see Fig. 12).

In the case where the gas cylinder 21 is held by the socket support section 42 in the foregoing manner, the human operator shifts the operating lever 82 to the fuel supply position P1 as indicated by an arrow J so that the curved portion 102a abuts against On the retaining rod 46 (left leg portion 91). The fuel contained in the helium gas cylinder 21 can be supplied to the gas engine 12 by shifting the operating lever 82 to the fuel supply position P1 in the aforementioned manner.

14A and 14B are views of an exemplary manner in which the retaining rod 46 of the receiver mechanism 25 is disengaged from the gas cylinder 26. As shown in FIG. 14A, the human operator places his finger on the finger placement portion 47c to lift the locking fastener 47 as indicated by an arrow K, and thereby the locking end 47b of the locking fastener 47 and the engaging portion 48 are The engaging groove 48b is disengaged.

Then, the human operator pivots the holding lever 46 upward about the left proximal end and the right proximal end 91a as indicated by an arrow L, so that the curved portion 102a is moved upward by the left leg portion 91, and the operating lever 82 and the curved portion 102a The movement moves in a pivotal manner in an interlocking relationship.

When the retention lever 46 is pivoted upward about the left proximal end and the right proximal end 91a as indicated by the arrow L in FIG. 14B, the right leg portion 91 of the retention lever 46 begins to abut against the barrier interlocking section 38. On the protrusion 117. Therefore, as the retaining lever 46 continues to pivot further upward as indicated by the arrow L, the projection 117 moves upwardly in an interlocking relationship with the retaining lever 46. That is, the shutter member 37 pivots upward about the support pin 106 as indicated by an arrow M.

Figure 15 is a view of one of the exemplary ways of disassembling the gas cylinder 26 from the receiver mechanism 25. The human operator withdraws the retaining rod 46 to the cancel position P4 above the receiver body 31, in response thereto, the shutter member 37 is moved up to the open position P6 and thereby withdrawn to the gas cylinder 26 above.

According to the current embodiment of the gas cylinder mounting structure as set forth above, the baffle interlocking section 38 can be engaged with the tank when the human operator operates the tank holding section 34 to cancel the holding of the gas cylinder 21 The operation of 34 shifts the shutter member 37 to the open position P6 in an interlocking relationship. In this manner, the current embodiment can minimize the time and labor for shifting the shutter member 37 to the open position P6, and thereby significantly enhance the uslium gas cylinder mounting structure and thus the usability of the working machine.

Further, in response to the movement of the curved portion 102a by the left leg portion 91, the operating lever 82 can be moved to the fuel blocking position P2. Therefore, when the holding of the box holding section 34 for the 气体 gas cylinder 21 (see FIG. 9) is canceled, the operating lever 82 can be interlocked to the pivotal movement of the holding lever 46 to move the shift valve 43 (see FIG. 4). Switching from the fuel supply position to the fuel blocking position. Therefore, when the gas cylinder case 26 is to be detached from the receiver body 31, it is not necessary to displace the shutter member 37 to the open position.

In addition, when the gas cylinder case 26 is to be detached from the receiver body 31, the human operator does not need to separately operate the shift valve 43 (the operating lever 82). Therefore, the gas cylinder case 26 can be detached from the receiver body 31 as easily indicated by an arrow N by a simple operation.

How to support the socket portion 61 of the gas cylinder 21 by the socket support section 42 is explained below with reference to Figs. 16A and 16B are views of an exemplary manner in which the fitting recessed portion 170 of the gas cylinder bin 26 is assembled over the socket support section 42.

As shown in Fig. 16A, the annular convex portion 128 (mounting concave portion 170) of the gas cylinder case 26 is formed such that the surface of the inner peripheral wall portion 171 is gradually inclined outward toward the distal end or the front end 171a, that is, The inner diameter of the inner peripheral wall portion 171 gradually increases toward the distal end front end 171a. For the inner peripheral wall portion 171 thus formed, the fitting recessed portion 170 has an increased inner diameter D at the distal end 171a.

When the socket portion 61 of the gas cylinder 21 is mounted to the socket support section 42 as indicated by an arrow O, it is contemplated that the central axis 181 of the socket portion 61 is offset from the central axis 180 of the socket support section 42. A distance S (Fig. 16A).

However, in the current embodiment, if the fitting recessed portion 170 has an increased inner diameter D at the distal end 171a, even if the central axis 181 of the socket portion 61 is offset from the central axis 180 of the socket supporting section 42 At the time of the distance, the fitting recessed portion 170 (the distal end 171a) can also be properly fitted over the socket support section 42 (more specifically, the outer peripheral wall portion 75).

17A and 17B are views for explaining an example of an example of mounting the socket portion of the gas cylinder 21 housed in the cylinder case 26 to the socket support section 42. As shown in Fig. 17A, the inner peripheral wall portion 171 has the aforementioned gradually decreasing wall thickness when viewed in an axial sectional shape. Thus, the socket portion 61 can be easily guided axially into alignment with the socket section 42 by the human operator only roughly positioning the tapered peripheral wall portion 171 relative to the outer peripheral wall portion 75.

As shown in FIG. 17B, the inner peripheral wall portion 28 of the gas cylinder box 26 is fitted over the top portion 74 and the outer peripheral wall portion 75 of the socket support section 42. The socket support section 42 can suitably support the socket portion 61 by abutting the top portion 74 of the socket support section 42 against the flange 72 of the socket portion 61.

That is, in the case where the inner diameter of the inner peripheral wall portion 171 gradually increases toward the front end or the distal end thereof, the socket of the gas cylinder 21 accommodated in the gas cylinder case 26 can be easily easily obtained without much time and effort. Portion 61 is mounted to the socket support section 42.

Further, the opening portion 27 of the gas cylinder case 26 can be hermetically closed by the outer peripheral wall portion 75 by fitting the inner peripheral wall portion 28 into the outer peripheral wall portion 75. In this way, the socket support section 42 can be closed by means of the gas cylinder case 26 so that foreign matter such as sand and dust can be prevented from entering the socket support section 42 (specifically, the nozzle receiving portion 65).

An exemplary manner of mounting the hinge pin 153 to the hinge section 124 is set forth below with reference to Figures 18 and 19. 18A and 18B are views of an exemplary manner of inserting the hinge pin 153 into the upper hinge portion 162 of the hinge section 124.

As shown in FIG. 18A, the human operator positions the lower hinge portion 151 between and is coaxial with the upper left hinge portion 162 and the right upper hinge portion 162, and then inserts the hinge pin 153 to the upper left as indicated by an arrow P. In the hinge portion 162.

Then, as shown in FIG. 18B, the human operator inserts the right end portion 153b of the hinge pin 153 into the left upper through hole 163 such that the right end portion 153b abuts against the left fall prevention protrusion 165. Then, as indicated by an arrow Q, the human operator pushes the hinge pin 153 deeper into the upper left through hole 163 while elastically deforming or indenting the left fall prevention protrusion 165 via the right end portion 153b of the hinge pin 153. in.

19A and 19B are explanatory views of an exemplary manner in which the upper hinge portion 162 and the lower hinge portion 151 are interconnected via a hinge pin 153. As shown in FIG. 19A, the human operator pushes the hinge pin 153 further deeper into the upper left through hole 163 in the case where the left fall prevention protrusion 165 is elastically deformed or collapsed as indicated by the arrow Q. .

Then, as shown in FIG. 19B, the human operator continues to push the hinge pin 153 further into the left upper through hole 163 as indicated by the arrow Q, so that the hinge pin 153 passes through the through hole 163 and the right end of the hinge pin 153 The portion 153b reaches the upper through hole 163 of the upper right hinge portion 162. Then, the right end portion 153b of the hinge pin 153 abuts against the right fall prevention protrusion 165.

Then, once the left end portion 153a of the hinge pin 153 passes over the left anti-dropout projection 165, the left anti-drop projection 165 is restored from the depressed state to its original protruding state, and the left anti-dropout projection 165 thus restored The abutment abuts against the left end portion 153a of the hinge pin 153. In this way, the upper hinge portion 161 (the upper left hinge portion and the upper right hinge portion 162) and the lower hinge portion 151 are interconnected via the hinge pin 153.

Since the left end portion 153a of the hinge pin 153 provides the left anti-drop projection 165 while the right end portion 153a of the hinge pin 153 provides the right anti-drop projection 165, the left anti-drop projection and the right anti-drop projection 165 The hinge pin 153 can be effectively prevented from accidentally falling off from the hinge section 124, which can enhance the usir gas cylinder mounting structure and thus the usability of the working machine.

It should be understood that the sputum gas cylinder mounting structure of the present invention is not limited to the preferred embodiments set forth above and may be modified or altered as desired. For example, although the preferred embodiment has been described as being applied to a push-type cultivator, the invention is also applicable to other types of work machines, such as lawn trimmers, outboard engines, generators, and the like.

Further, although the inner peripheral wall portion 171 of the fitting recessed portion 170 has been described as having a circular cross-sectional shape, it may have any other cross-sectional shape such as a polygonal cross-sectional shape.

Further, the 匣 gas cylinder 21, the receiver mechanism 25, the gas cylinder case 26, the socket support section 42, the socket portion 61, the annular convex portion 128, the fitting concave portion 170, the inner peripheral wall portion 171, and the like may have Shapes other than those illustrated above and illustrated in the figures.

The basic principle of the present invention is well suited for use in a helium gas cylinder mounting structure in which a one-inch gas cylinder is housed in a cylinder and that the cylinder is mounted to a cylinder mounting mechanism.
